HINGE FOR FOLDING CHAIRS.

Application filed August 5, 1921, Serial- No. 489,981. Renewed February 28, 1925. I

To all whom it may concern:

Be it known that We ARTHUR F. DERSE, a citizen of the United states, and a resident of Union Course, in the county of Queens 15 and State of New York, and WILLIAM B. lViLsHUsnN, a citizen of the United States,

and a resident of Mount Vernon, in the county of Westchester and State of New York, have invented a new and useful Hinge for Folding Chairs, of which the following is a specification.

This invention relates to folding chairs of the character disclosed in application Serial No. 410,840 filed September 17, 1920.

In that application a two-part seat of relatively rigid material is pivoted to pivotally connected legs and the centre pivot connecting the two parts of the seat together consists of a wire bent into three lengths, one, a long length, and the other, two short lengths that are coaxial with each other and parallel to the long length. When subjected to stresses the wire is apt to become distorted.

155 The main object and. feature of this in Figure 3 is a sectional View on the line 3-3 of Figure 2.-

1 indicates the legs pivotally connected together in the manner described in the application referred to and also pivotally connected, at 2, to the two-part seat 3 and 4:.

5 indicates the central hinge connecting the two parts of the seat and consists, as shown, of a wire bent into two set-s of parallel lengths, the sets being arranged end to end. One set is indicated by the lengths 6 and 7 and the other by the lengths 8 and 9. It will be observed that the lengths of each set are connected together as at 10, and also that one length, 6, of one set is connected by a cross-over portion 11, to that length, 9, of the other set that is not coaxial therewith. In this Way, lengths 6 and 9, which are connected together by crossover portion 11, re-

ceive stresses that act in opposite directions and therefore tend to neutralize each other by reason of said cross-over portion.

WVe claim:

A hinge including a wire bent into tWo sets of parallel lengths, said sets being arranged end to end, and the lengths of each set being connected together, one length of one set being connected by a crossover portion to that length of the other set that is not coaxial therewith.

Signed at Brooklyn, in the county of Kings, and State of New York, this 30th day of July, 1921.
